How did the Battle of Umm Diwaykarat end the Mahdist resistance?

The Battle of Umm Diwaykarat, which took place on November 24, 1899, served as the final engagement that effectively crushed the remaining Mahdist resistance.12

Following the decisive defeat of the Mahdist forces at the Battle of Omdurman in 1898, the British spent the subsequent year consolidating their control over the Sudan. During this time, the Mahdist leader ‘Abd Allāh—who had succeeded the original al-Mahdī—remained at large with a remnant of his army.12

In November 1899, an Anglo-Egyptian force of approximately 3,700 men, commanded by Sir Reginald Wingate, was dispatched to Kordofan to engage these forces. During the ensuing battle at Umm Diwaykarat, the Mahdist remnants were defeated, and ‘Abd Allāh was killed in the fighting, marking the end of the organized Mahdist movement.12
